Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Air Duct Cleaning in Norwalk, CA
Dryer vent cleaning in Norwalk is a different job than it is ten miles west, because this city sits where the I-5 and I-605 meet, with Santa Fe Springs’ industrial zone pressing against the northern border. We find diesel soot inside dryer exhaust runs here, mixed with the usual lint, and in older tract homes that means a vent line that can’t breathe. Call (806) 606-6902 and we’ll give you a written price before any panel comes off.
Why Norwalk Homes Are Different
Norwalk’s housing stock is mostly post-WWII single-family tract homes built between the mid-1950s and early 1970s. That’s not trivia; it’s the single biggest predictor of what we see inside ductwork here. Many of those homes still run their original forced-air systems through unconditioned attics, with flex duct that has been baking in 140°F summer heat for fifty-plus years. The liner degrades, the mastic seals at joints fail, and the duct boot connections pull away from registers. When that happens, the system isn’t just leaking conditioned air; it’s actively drawing super-heated, particulate-heavy attic air into the living space.
The freight corridor factor is just as real. Prevailing wind patterns push exhaust from the I-5 and I-605 toward this pocket of the LA Basin. We regularly pull registers in Norwalk homes near the interchange and find a thin, greasy black film coating the duct interior, a diesel-soot signature that shows up far less often a few miles south in Cerritos or west in Downey. For Norwalk homeowners, air duct cleaning is fundamentally a freight-pollution and industrial-adjacency problem, not just a dust problem. That changes what we look for, what we photograph, and what we recommend.
Our Main Norwalk Services
Most Norwalk homeowners call us about two things: the ductwork that circulates air through their home, and the HVAC equipment that moves it. Here’s what each job looks like in this city.
Air Duct Cleaning in Norwalk
A full Air Duct Cleaning in Norwalk means cleaning every supply and return run, the plenum, and the trunk lines, not just vacuuming the registers. In Norwalk’s older tract homes, we typically find a mix of construction debris from decades past, degraded flex duct liner, and that diesel-soot film near the freeway corridors. Every run is photographed before and after, and the photo record comes with the job as a standard deliverable, not an upsell.

HVAC Cleaning in Norwalk
HVAC Cleaning in Norwalk covers the evaporator coil, blower motor, condensate pan, and the cabinet itself. When attic temperatures climb past 140°F, coil surfaces collect the same fine carbon soot that coats ducts, which reduces heat transfer and forces the system to run longer cycles. We clean the coil and blower assembly, then document the before and after with the same photo record we use on every CleanRun job.

AfterDryer Vent Cleaning in Norwalk

Dryer vent cleaning in Norwalk means dealing with a vent run that has been collecting lint for years, often in a home built when dryer ducts were routed through the attic with more bends than they should have. Add the fine particulate load from the I-5/I-605 corridor, and you get a situation where a vent line that should let air move freely is instead holding heat and lint against a hot dryer element. We treat every Norwalk dryer vent as a fire-risk inspection first and a cleaning second, and we document what we find with before-and-after photos of the full run. If you haven’t had your vent looked at since buying a 1960s tract home in Norwalk, Dryer Vent Cleaning is where you start.
Dryer Vent Inspection
Signs you need it
Clothes take two or three cycles to dry, the dryer housing gets unusually hot to the touch, or you notice a burning smell when the dryer runs.
What it costs in Norwalk
Inspection-only runs $95 to $195, but most Norwalk homeowners combine it with cleaning for $120 to $280 total.
How we do it
We run a camera through the full vent run from the dryer connection to the exterior termination, checking for blockages, failed joints, and the greasy soot film common near the I-5/I-605 corridor.
Vent Cleaning
Signs you need it
You can see lint collecting around the exterior vent opening, or the dryer’s airflow at the exhaust point feels weaker than it used to.
What it costs in Norwalk
Full vent cleaning runs $120 to $280 depending on run length and how much soot and lint has accumulated.
How we do it
We use negative-pressure extraction with rotating brush agitation to pull lint and debris out of the vent while preventing it from blowing back into the laundry area.
Lint Removal
Signs you need it
The dryer cycles fine, but the vent flap outside barely opens when the dryer runs, suggesting a substantial blockage inside the run.
What it costs in Norwalk
Heavy lint removal starts at $120 and can go to $300 if we find a nearly fully blocked run, which we do more often in Norwalk than in coastal cities.
How we do it
We remove the lint, photograph the blockage before removing it, and leave you with pictures of a clear vent run from the dryer to the exterior cap.
Bird Guard Installation
Signs you need it
You hear birds or scratching near the exterior vent opening, or you find nesting material around the vent cap.
What it costs in Norwalk
Bird guard installation runs $75 to $150, including the guard and the labor to mount it correctly.
How we do it
We install a louvered metal guard over the exterior vent termination that allows air to exit while preventing birds, rodents, and debris from entering.
What Dryer Vent Cleaning Costs in Norwalk
| Item | Typical range in Norwalk |
|---|---|
| Vent inspection only | $95 - $195 |
| Full vent cleaning | $120 - $280 |
| Bird guard installation | $75 - $150 |
How often should I have my dryer vent cleaned in Norwalk?
Every 12 to 24 months for most Norwalk homes, and every 12 months if you live near the I-5 or I-605. The soot and particulate load in this part of the Basin makes lint stickier and blockages form faster. Call (806) 606-6902 and we’ll confirm what your vent actually needs.
Why does my Norwalk dryer vent clog faster than my parents’ vent in Orange County?
The freight corridor particulate combines with lint to form a denser, stickier buildup. Add older 1950s-1970s vent routing with extra bends, and airflow slows enough that debris accumulates much faster. We photograph what we find so you can see it for yourself. Call (806) 606-6902 for a written price.
Duct Repair & Sealing in Norwalk

Duct repair and sealing in Norwalk almost always comes down to age and heat. Homes built between the mid-1950s and early 1970s have flex duct that has spent fifty-plus summers in 140°F attics, and the mastic seals at every joint and boot connection are failing, pulling super-heated, soot-heavy attic air into the system. That leaking return air is pulling diesel particulates from the I-5/I-605 corridor into rooms where people sleep. Every Duct Repair & Sealing job starts the same way: we open the system, photograph the failed seals and deteriorated liner, and hand you a written scope before any repair work begins.
Duct Sealing
Signs you need it
Some rooms are noticeably warmer or cooler than others, your energy bills climb in summer, or you can see dust streaks around ceiling registers.
What it costs in Norwalk
Sealing accessible duct runs and boots runs $350 to $800 depending on how many joints have failed.
How we do it
We locate every failing joint with a visual inspection, photograph each one, then apply mastic sealant to all accessible seams and boot connections to stop the air exchange with the attic.
Flex Duct Repair
Signs you need it
The inner liner has pulled away from the outer jacket, you can see visible kinks or tears in attic duct runs, or rooms aren’t reaching the temperature set on the thermostat.
What it costs in Norwalk
Replacing a damaged flex duct section runs $400 to $1,000 per run depending on length, diameter, and how difficult the attic access is.
How we do it
We remove the degraded flex section, install a new properly-sized run with clean connections, seal every joint, and photograph the finished work before we leave.
Duct Insulation
Signs you need it
Your attic ducts feel hot to the touch in summer, condensation forms on duct exteriors, or the insulation jacket has torn away from the liner.
What it costs in Norwalk
Adding or replacing insulation on duct runs runs $300 to $1,200 for a typical Norwalk single-story tract home, depending on total linear footage.
How we do it
We wrap the duct runs with the correct R-value insulation for Norwalk’s summer attic temperatures, seal all seams, and document every section we covered.
What Duct Repair & Sealing Costs in Norwalk
| Item | Typical range in Norwalk |
|---|---|
| Duct sealing (accessible) | $350 - $800 |
| Flex duct replacement | $400 - $1,000 per run |
| Duct insulation | $300 - $1,200 |
Can you seal ducts in a Norwalk attic in summer?
Yes, but we schedule Norwalk attic work in the early morning when possible, because attic temperatures above 140°F make sealants cure too fast and make the work slower. The heat also degrades old mastic faster, which is why we see so many failed seals here. Call (806) 606-6902 and we’ll give you a written scope before any work starts.
Why do my Norwalk ducts leak more than my previous house in a newer development?
Your Norwalk tract home likely has original or minimally-upgraded ductwork from the 1950s to 1970s. Decades of 140°F attic summers have degraded the liner and failed the mastic at every joint, which means air you paid to condition is leaking into the attic. We photograph every failure before we repair it so you can see the difference. Call (806) 606-6902 for a written estimate.
Air Quality & Sanitizing in Norwalk

Air quality and sanitizing in Norwalk is about what’s coming into your ducts from outside, and what grows inside them once it’s there. The I-5 and I-605 freight corridors load the air with diesel exhaust particulates and fine carbon soot that settle inside ductwork, and when those ducts run through unconditioned attics, temperature swings create condensation that lets mold and bacteria take hold. That’s the Norwalk baseline: a particulate-heavy, occasionally damp, warm duct system that can carry odors from the industrial corridor into bedrooms. After we clean your ducts, Air Quality & Sanitizing is what keeps them from re-contaminating, and we photograph every step so you can see what we found before we treat it.
Mold Treatment
Signs you need it
You see dark staining around registers, smell a persistent musty odor, or visible mold growth is confirmed inside a duct run during inspection.
What it costs in Norwalk
Mold treatment for duct interiors runs $450 to $1,200 depending on the affected square footage and whether we need to remove and clean register covers.
How we do it
We apply an EPA-registered antimicrobial product to affected duct surfaces, photograph the contaminated area before treatment, and document the cleaned surface afterward.
Odor Removal
Signs you need it
A persistent diesel-exhaust or industrial smell lingers in the house even with windows closed, or a musty odor returns within days after cleaning.
What it costs in Norwalk
Odor removal runs $250 to $500 and often includes treating the evaporator coil and blower cabinet where odor compounds collect.
How we do it
We locate the source of the odor, whether it’s soot film on duct interiors, a contaminated coil, or both, then treat the affected surfaces with a neutralizing antimicrobial and document the result.
Purifier Install
Signs you need it
Household members have worsening allergies or respiratory irritation, especially on high-traffic days on the I-5 and I-605, or dust and soot settles on surfaces within days of cleaning.
What it costs in Norwalk
Whole-home air purifier installation runs $800 to $2,500 including the unit and labor, with final price depending on the system type and your furnace’s configuration.
How we do it
We install the purifier in the supply plenum so treated air circulates through every room, wire it into the furnace, and verify the system’s pressure drop to ensure airflow isn’t compromised.
UV Light Installation
Signs you need it
You’ve had repeated mold or bacteria issues near the evaporator coil, or you want to keep the coil surface from becoming a biological growth point.
What it costs in Norwalk
UV light installation runs $600 to $1,200 depending on the fixture type and whether we install it in the coil area, the return plenum, or both.
How we do it
We mount the UV fixture with direct line-of-sight to the coil surface, wire it to run continuously when the blower operates, and photograph the final installation.
What Air Quality & Sanitizing Costs in Norwalk
| Item | Typical range in Norwalk |
|---|---|
| Mold treatment (duct interiors) | $450 - $1,200 |
| Odor removal | $250 - $500 |
| UV light installation | $600 - $1,200 |
Will air quality treatment actually help with diesel soot from the freeway?
It helps significantly, because the soot settles inside your ductwork and gets redistributed every time the blower runs. Cleaning removes the particulate load, and sanitizing prevents biological growth in the residue that remains. Call (806) 606-6902 and we’ll give you a written price for the full scope.
How do I know the sanitizing actually worked?
You get a documented photo record of every treated surface, before and after, as part of the job. You’ll see the contamination we found and the cleaned surface we left. If anything doesn’t meet the standard, the 365-Day Done Right Promise covers a re-treatment at no cost. Call (806) 606-6902 to schedule.

FAQs About Air Duct Cleaning in Norwalk
No permit is required for routine duct cleaning, dryer vent cleaning, or duct sealing in Norwalk. If the work involves replacing a furnace or making structural changes to the venting system, that’s a different scope and may require city approval. We’ll tell you in writing if your job crosses that line before any work starts.
Most Norwalk jobs can be scheduled within one to two business days. Attic work in summer gets scheduled for early morning when possible, because 140°F attic temperatures slow down sealant work and make the job harder on our crew. Call (806) 606-6902 and we’ll find a slot that works.
